Re: [T5] SelectObject component added to the Wiki
Posted by Davor Hrg <hr...@gmail.com>.
I've created a simpler version, this is as simple as I could make it
without requiring changes to select component.
http://wiki.apache.org/tapestry/Tapestry5HowtoSelectWithObjects
I belive that having objects in the list is a common case enough
so simplifying a task like this should be a goal later on in development....

for sure, this solution is way more complicated than it should be, but
tapestry limit us too much in this point(as it does in the DatePicker
too)... i hope there will be some better solution on the next release.

Re: [T5] SelectObject component added to the Wiki
Posted by Davor Hrg <hr...@gmail.com>.
If you like digging into tapestry I suggest you start
by removing beanutils dependancy and adding:
@Inject
private PropertyAccess propertyAccess;
into SelectObject.java
after that use propertyAccess instead of beanutils...
....
I'm currently building a version that doesn't need
SelectObject component, but uses normal select component.
The code is more complicated than it should be, so I suppose
I might post an enhancement ticket for the Select component.
...
if you like to start with working code ...
here's the changed version that works for me ...
